1b all 'whom itl-may concern.'

Be itknown that',I,gPLEA sANT A. Hun DLEsToN, a citizen of the UnitedStates, re-

siding at Oklahoma, in the countyof Oklahema and State of Oklahoma, haveinvented certain new and .useful Improvements 1n Electric IlluminatingAlarm-Clocks, of

` which thefollowing is a specification.

bell and lighting an electricA lamp at will or at apredetermined time.

`Another object is to provide means by which the electric bell may beput out of .cir-

Svpeccation of Letters Patent cuit and silenced, while the electric lampremains lighted; or the .lamp may be lighted at will or at apredeterminedtime. i

I arrange the apparatus so that it may be connected by means of theusual. flexible twin conductor cord and attachment plug to -a wallsocket connected to the electric lighting circuit; 4or in case there isno available lighting 'circuit,. the operating current may preferably besupplied by a set of batteries preferably inclosedwithinthe apparatus.

In theaccompanying drawings, Figure l is an end elevation vof anapparatus embodyin -g .my invention and showing in dotted linesthemanner of attaching an ordinary form of alarm. c1ock; Fig. 2 is alongitudinal section thereof; Fig. 3 is` a detail top plan view of theclock-actuated. trigger and switch-arm; Fig. 4, is a diagram of theelectric circuits showing the apparatus connected to a'house electriclighting circuit;

end yof the standard 7 terminates in a horizontal arm which carries thetrigger and switch mechanism to be` actuated by the striking hammer 12of the alarm clock. The switch-arm 14 of the trigger vmechanism ispivotally mounted on the arm 7 and is provided with a tooth 15, adaptedto be engaged by the dog'16, of the trigger 18. l/Vhen the hammer 12 ofthey alarm clock is actuated, striking the trigger 18, the switch-arm 14is disengaged and is snapped by the spring 13, against the insulatedcontact plate and stud 14%, thereby closing the circuit between thewires 32 and 33.

The alarm clock may be of the ordinary type and may be slipped in thedirection of manner indicated in Figs. 1 and 4, so that cuits within theapparatus-when operated by batteries.

A casing, 1, which maybe constructed oi metal, wood or other suitablematerial, is provided with a lamp socket 2, and electric pilot lamp 3,of low voltage,`preferably 3 or 4 volts.`

A n electric alarm 4, is secured within .the casing', the bell 5extending through the wall, and a'set of battery cells 6 may also beinclosed.

To one end of the casingl is secured a skeleton frame having upright'posts or standards 7, 7EL connected by a cross-bar 8. Spring clips 9,may be secured to the standards to engage the sides of the clock 10 andmaintain it in proper position. The upper the alarm apparatus may beconveniently connected by vmeans of a flexible electric cord connection.

One contact of the room lamp switch 25, usually of the snap-switch type,is connected to one of the mains 27, the room lamp 28 being connected totheother main and to the other switch contact. The wall-socket 29 isalsol connected to the contacts of the room switch. The alarm apparatusis provided lwith plug contacts 30, which can be placed in circuit withthe lighting mains by means of a flexible cord conductor 32 connectingthe plug contacts with the wall? socket 29. The circuits will be readilyunderstood from Fig.4 1 and the diagram,

Fig. 4.

The operation will be apparent to those skilled in the art from theabove description of the apparatus. Assuming that the hour previouslyset, the hammer 12 strikesthe trigger 18, releasing the clock switch arm14, which is thereupon swung around 'by spring 13, into engagement withthe con tact 14, therebyx completing the circuit from the mains 27, andcausing the electric bell 4: to ring and lighting the room lamp I28 andpilot lamp 3. This will arouse the occupant of the room, who will closethe room switch 25, thereby short-circuiting the bell and pilot lamp butleaving the room lamp 28 lighted. f

lf it is desired to use my apparatus in a room which is not providedwith 'electric lighting or it is not convenient to connect a wall socketto the mains, my apparatus' can be operated by means of the batterycells 6, which may be carried within the casing 1. With the circuitsarranged as shown in Fig. 4c, the battery switch 35 is closed and thealarm on the clock is set as previously described. When the alarm isactuated at the predetermined hour, the switch 14 is closed in themanner described, thereby closing the battery circuit through theelectric bell 4. and pilot lamp. The occupant of the room, upon beingaroused can close the bell switch 37, thereby short-circuiting andsilencing the bell, while leaving the lamp 3 lighted, and

he `may leave the lamp lighted or turn itV out at pleasure. v

It will be understood that in the arrangement shown in Figs. 1 and 4,either the room lamp or the. pilot lamp, or both, may be lightedwhenever desired by closing the` proper switches, independent of thealarm. When the apparatus is operated bythe batter);r cells, thecircuits may be connected as` I have described the constructionillustrated in the drawings'in detail for Vthe purpose of disclosing anembodiment of my inven-v tion but it 'is to be understood that variouschanges can be made therein by those skilled in this art Withoutdeparting from the spirit y incassa of my invention. Thus, forillustration, the

switch arm 14 might be closed directly by the blowof the hammer l2,instead of being spring-actuated, and dispensing with the trigger, andother obvious changes may be made.

I claim'z- 1. Alarm mechanism comprising a clock provided with astriking hamnrer, an electrically operated alarm, circuit connectionsleading from said alarm to a source of electric current, a casing havinga standard or frame, a spring-actuated switch secured thereto andconnected in circuit with said alarm, and a trigger carried by saidframe adjacent said hammer and adapted to hold said switch in openposition against the tension of said spring until released by saidhammer.

2. Alarm mechanism comprising a clock provided with a striking hammer,an electrically operated alarm, circuit connections leading from saidalarm to a source of elecframe, a spring-actuated switch secured theretoand connected in circuit with said alarme, a/trigger carried by saidframe adjacent said hammer and adapted to hold said switch in openposition until released by said hammer, and means for short-circuitingsaid alarm at will, thereby permitting the lamp to remain in circuit.

3. The combination with a clock having a striking'member adapted to beautomatically operated at a predetermined time, of a casing having aframe provided with'means to receive and clamp the clock, switch mech-lanism carried by the 'casing and located adjacent said striking member,a source of electric currents, a plurality of electrically energizeddevices, conductors connecting said switch mechanism with saidelectrically energized devices, and means for short-cirtric current, acasing having a standard or" cuiting one of said devices While leavingthe p other device vin circuit with saidv source.

ln testimony whereof I affix my signature in presence of two witnesses.

PLEASANT A. HUDDLESTON.
